Materials:
• Starch
• Aluminum foil
• Sun dried lanzones peelings
• Commercial mosquito coil
• Mortar and pestle
• Basin/containers
• Food coloring
• Alcohol
Procedure:
1. Make sure the lanzones peelings were sun dried for a few days.
2. When fully dried, pulverize using a mortar and pestle.
3. Mix an equal amount of starch and pulverized lanzones peelings.
4. Add water to make a paste-like consistency. Mix thoroughly.
5. Now, get the commercial mosquito coil and with the foil, make a mold.
6. Pour the mixed starch and lanzones into the mold and let the mixture dry. You now have a mosquito coil.
The fruit peel of Lansium domesticum, var. pubescens ( thicker than that one of the sweeter var. domesticum ) exudes a white sap/latex containing mosquito repelling triterpenes ( lansionic acid p.e. ). The dried peel is burned and produces an aromatic, white smoke ( white from the sap and some remaining water ). https://answers.yahoo.com/question/index?qid=20080204035618AAgUwZG According to report, it contain approximately six percent lansium acid, a toxic substance applied on arrow tip. Lasium acid can also be found in bark and can kill frogs by stopping heart beat. However, there are no reports about its affect to humans. And due to the toxic it can drive the mosquitoes aways, but you need to dry the lanzones peelings for a few days, cause the peeling will burn slowly to make it a mosquito repelant. http://www.answers.com/Q/What_chemical_properties_of_lanzones_peelings_that_can_repel_mosquitoes Background of the Study
Mosquitoes have been the problem of many people for a long time. Therefore, it is important that everyone would take precautionary countermeasures in order to prepare for the rainy season, which is usually the time when insects appear more frequently. And an example of a mosquito repellant is the mosquito coil or more informally known as “katol.” Our group has found out that mosquito coils can be made
